I would use batch action in photoshop for all your bitmaps to add some bleed

1. create new photoshop action using edit>canvas size 101% (with black background color preselected)
2. File>automate>batch with target folder containing your bitmaps

This can be done in a few minutes for hundreds of images at once.

EDIT: Do the same for your diffuse, bump, refl. etc. bitmaps as well, so you dont have to mess with different size/uv. And backup your files before :-)

Hi all. The problem with the original tap scene was caused by different behavior of standard bitmap vs coronabitmap and "no tilling" option. Clamp tilling didnt worked, because mask was cropped in a way, that it had no "bleed" and there are both black and white pixels on the edge. (see picture for better understanding) In crop mode black and white pixels on the edge are stretched to infinite and creates stripes on the object.

There are 3 solutions:
1. use some "bleed" on the masks, so all pixels on the edge of the bitmap are black. Then crop option in tilling mode will work well. (best option)
2. use standard bitmap for masks
3. use composite map to comp mask with black color background. Then you can use "no tilling" option in coronabitmap.
